<p><b>Abstract:</b> <p style="margin-left:0cm; margin-right:0cm; text-align:justify"><span style="font-size:12px"><span style="font-family:Verdana,Geneva,sans-serif">This study reports the grafting of poly(ε-caprolactone) (PCL) on guar gum (GG) by in-situ ring-opening polymerization using tetra(phenylethynyl)tin (Sn(C&equiv;CPh)<sub>4</sub>) as catalyst. The hydroxyl groups of guar gum act as initiators for ε-caprolactone ring-opening polymerization and the resulting poly(ε-caprolactone) binds covalently to the polysaccharide. The highest stability of Sn(C&equiv;CPh)<sub>4</sub> allows the reaction in open-air, thereby reducing the cost of the synthesis and provides polymers with high molar mass. Fourier transform infrared (FTIR) and the long-term stability of the suspension PCL-g-GG in dichloromethane confirmed the effectiveness of grafting of PCL into GG. The size exclusion chromatography (SEC) results show that the molar masse of grafted PCL could be modulated by varying the amount of guar gum. From thermogravimetric analysis and differential scanning calorimetry results the thermal stability of PCL-g-GG is greatly improved with different content of guar gum, also the melting temperature and crystallinity increased by increasing the GG content. The scanning electron microscopy (SEM) analyses showed the good adhesion between GG and PCL with 5% of GG contents. It was also revealed by contact angle measurements that the grafting of PCL to GG leads to a decrease of hydrophobicity of PCL. The micro-indentation hardness properties of the prepared PCL-g-GG were significantly improved, as compared to neat PCL.</span></span></p> </p> </div> </div> <h1 style="text-align: left;">Speakers</h1> <div class="shedule-box color-1" data-toggle="modal" data-target="#session2208"> <div class="col-xs-2 padding-0"> <i class="sml-img-box"><img src="https://s3.amazonaws.com/longdom/members/d-20-1636.jpg" alt="Ahankari Sandeep Sureshrao"></i> </div> <div class="col-xs-10 padding-0"> <div class="schedule-details"> </div> <div class="schedule-topic"> <h3><a href="https://www.longdom.com/biopolymer-2021/speaker/ahankari-sandeep-sureshrao">Ahankari Sandeep Sureshrao</a></h3> <span class="schedule-titles"></span> <small><i>India</i></small> </div> </div> <div class="col-xs-12 padding-0 text-left"> <p><b>Title:</b> Recent Advances in the development of supercapacitor components employing nanocellulose based polymer composites </p> <p><b>Abstract:</b> <p style="margin-left:0cm; margin-right:0cm; text-align:justify"><span style="font-family:Verdana,Geneva,sans-serif"><span style="font-size:12px">With rapid fossil fuel consumption and ecological concerns, alternative options of green energy development and its efficient storage technology is an emergent area of research. Nanocellulose (NC) is observed a very-promising, sustainable and environmentally friendly nanomaterial for green and renewable electronics for advanced electrochemical energy conversion/conservation devices. NC has high strength, modulus, and aspect ratio. It is stable in most of the solvents and the stability has wide electrochemical window. Hence it can be used as a separator, electrolyte, or binder material also. The nano-order scale of NC offers a very high surface area that assists in controlling the pore structure in separators. It offers a perfect diffusion path for an electrolytic solution and facilitates the transport of ions. If used as an electrode, NC provides mechanical strength and flexibility to such electrodes (films or aerogels) and offers very high surface area that improves its capacitive performance. Conductivity of such an electrode can be increased by loading it with conductive carbonaceous materials like CNTs, graphene oxides (GO) etc. </span></span></p> <p style="margin-left:0cm; margin-right:0cm; text-align:justify"><span style="font-family:Verdana,Geneva,sans-serif"><span style="font-size:12px">The pore size and its distribution in NC affect the electrolyte uptake, ionic conductivity and hence the performance of supercapacitor. It is very much required to control these parameters and prevent the collapse of the web structure of NC for improved performance in energy storage systems in 2D structures. To impart flexibility to the electronic storage systems, the processing route to be selected must be the one that can maintain the high aspect ratio of the NC. Solvent casting, filtration methods maintain the aspect ratio of the NC but are not industrially viable techniques. On the contrary, extrusion and film making can be a commercial method provided an in-depth analysis of the effect of various processing parameters on the properties of resultant nanocomposites is done. Aspect ratio of the melt processing technique is found lesser compared to laboratory techniques. </span></span></p> <p style="margin-left:0cm; margin-right:0cm; text-align:justify"><span style="font-family:Verdana,Geneva,sans-serif"><span style="font-size:12px">NC being sustainable and biodegradable with remarkable and tailoring properties, ubiquitously proves to be a demanding substrate in making flexible electrodes and separators in supercapacitors. To enhance the energy density further, the design and manufacturing aspects of nanocellulose based aerogels and 3D structures are also being explored recently. More efforts in the development of industrially viable processing technique that can manufacture big sized electrodes are required. Authors will discuss some ideas of manufacturing large sized electrodes. Definitely, challenges are there and more efforts are required to warrant such sustainable materials in energy applications keeping in mind the environmental protection. At a first place, high manufacturing cost and time are still the concerns with nanocellulose production. New ways to produce nanocellulose with large scalability and low cost should come up.</span></span></p> <p style="margin-left:0cm; margin-right:0cm; text-align:justify"> </p> <p style="margin-left:0cm; margin-right:0cm; text-align:justify"> </p> </p> <p><b>Biography:</b> <p><span style="font-family:Verdana,Geneva,sans-serif"><span style="font-size:12px">Dr. Sandeep Ahankari is working as an Associate Professor in the School of Mechanical Engineering at VIT University, Vellore, TN, India.

To overcome the problems posed by synthetic plastic based wastes, Government organizations as well as research institutions around the world are focusing on fabrication of bioplastics from renewable resources. Soy protein isolate (SPI) is an important biopolymer from which bioplastics or biofilms can be easily prepared either by solution casting or compression molding methods (1). Eighteen amino acids constitute SPI based biopolymer and the presence of these amino acids imparts different properties depending on hydrophobic or hydrophilic based functional groups of their side chain. Several nanoparticles such as MMT, CNTs and carbon nanoparticles have been incorporated in SPI to increase the material properties of SPI based plastics (2-4). In this work, CPI (citric acid poly ethylene imide carbon dot) and 0.05 to 0.2% CCG (citric acid glycine carbon dot) have been incorporated in SPI. Glycerol plasticized SPI films at different contents (0.1 to 0.5%w/w w.r.t SPI) of CPI and (0.1 to 0.5% w/w w.r.t SPI) of CCG were fabricated. CCG and CPI incorporated SPI films were subjected to FT-IR studies for structural characterization in addition to mechanical properties and water uptake tests. There is generation of peak at 1728 cm<sup>-1</sup> after incorporation of 0.15 and 0.2 % of CCG in SPI as compared to neat SPI. Mechanical properties results indicated tensile strength of 7.8 MPa and 7.6 MPa for 0.5% CPI and 0.15% CCG incorporated SPI films, respectively as compared to tensile strength of 5.88 MPa for neat SPI films. Elongation at break was found to be lowest i.e., 7.3% for 0.15% CCG incorporated SPI as compared to SPI films incorporated at all the contents of CPI and CCG.. Interestingly, the water uptake of CCG and CPI incorporated SPI films were ~36% as compared to water uptake of ~158% for neat SPI films. This may be attributed to interactions between functionalized groups of CCG or CPI nanoparticles with amino or carboxyl functional groups of SPI. CCG and CPI incorporated SPI films were also subjected to antimicrobial tests. This work gives an idea to fabricate functionalized carbon dot nanoparticles with reasonable mechanical properties and low water uptake. </span></span></p> </p> <p><b>Biography:</b> <p style="margin-left:0cm; margin-right:0cm; text-align:justify"><span style="font-size:12px"><span style="font-family:Verdana,Geneva,sans-serif"><span style="background-color:white">Dr Rakesh Kumar is an Associate Professor in Department of Biotechnology, Central University of South <span style="color:black">Bihar, India.

However, the design and formulation of an effective antimicrobial and antioxidant edible material by use of fully natural components is really a challenging process since it needs careful selection of natural components (biopolymers, plasticizers, active agents etc.), microbial target(s), and controlled release strategies considering the targeted food application (Yemenicio臒lu et al., 2020; Boyac谋 and Yemenicio臒lu, 1999). This presentation includes recent trends and state-of-the-art strategies applied to develop active edible films, coatings and pads that are formed by fully natural components and are really effective in the food system. Methods of achieving controlled release such as morphological tailoring (e.g. composites, blends, emulsions etc.), modification of hydrophilic/hydrophobic properties, cross-linking, encapsulation etc.; and methods of boosting active properties (e.g. use of hurdle concepts and synergetic interactions) have been presented with realistic examples of food applications. Emerging concepts such as activate-at-home type packaging and bioactive packaging are also discussed to increase attention in innovative potential of active packaging (Boyac谋 et al. 2016). This presentation focuses on expanding the horizons of scientists working in the fields of active packaging and natural active agents.   </span></span></p> </p> <p><b>Biography:</b> <p style="margin-left:0cm; margin-right:0cm; text-align:justify"><span style="font-size:12px"><span style="font-family:Verdana,Geneva,sans-serif">Ahmet Yemenicioglu took his PhD in 1998 from Department of Food Engineering at Ankara University where he joined to research team of Prof. Bekir Cemero臒lu.

Those also involve polymers which can be acquired from renewable resources that may be used to manufacture Bioplastics by using polymerization. </span><span style="color:#111111">There are mainly two types of Biopolymer</span><span style="color:black">, one that is obtained from residing organisms and any other this is produced from renewable resources however require polymerization. The ones created by means of living beings consist of proteins and carbohydrates. </span><span style="color:#111111">Unlike synthetic polymers,</span><span style="color:black"> Biopolymers have a well-marked shape. Those polymers have a uniformly distributed set of molecular mass and appear as an extended chain of worms or a curled up string ball under a microscope. This sort of polymer is differentiated based on their chemical shape. Examples of the maximum used biopolymers are chitosan, cellulose, carrageenans, alginate, polyesters, and proteins together with enzymes and DNA. </span><span style="color:#111111">The applications of biopolymers are immense and could be found in many fields </span><span style="color:black">such as food, pharmaceutical, cosmetics, agriculture, biomedicine and lots of chemical industries the use of enzymes. Those polymers play an essential role in nature. They are extremely beneficial in performing features like storage of energy, </span><span style="color:#111111">preservation and transmittance of genetic information and cellular construction</span><span style="color:black">. Sugar based polymers, such as Polyactides, evidently degenerate inside the human frame without producing any dangerous aspect results. This is the cause why they may be used for clinical functions. Polyactides are normally used as surgical implants. Starch primarily based biopolymers may be used for growing traditional plastic by using extruding and injection molding. Bioplastics are plastics derived from renewable biomass sources, such as vegetable fat and oils, corn, starch, straw, woodchips, food waste, etc. Bioplastic may be crafted from agricultural by using-products and additionally from used plastic bottles and </span><span style="color:#111111">other containers using</span><span style="color:black"> microorganisms. Common plastics, inclusive of fossil-gas plastics (additionally called petro based polymers) are derived from petroleum or Natural gas. Not all bioplastics are biodegradable non- biodegrade more </span><span style="color:#111111">readily </span><span style="color:black">than commodity fossil-fuel derived plastics. Bioplastics are usually derived from sugar derivatives, which include starch, cellulose, and lactic acid. As of 2014, bioplastics represented about 0.2% of the global polymer market. Bioplastics are the plastics which might be created by using biodegradable polymers. They may be currently being produced in massive quantity with the aid of microbial fermentation method in industries. Among all of the polyhydroxy, alkanoates, polyhydroxy butyrate or PHB is the most essential one as bio plastics. The conventional plastics, made from coal or oil are not biodegradable. They survive 100s of years and are a first-rate source of environmental pollution, often resulting in ecological imbalance. A heavy call for biodegradable plastic materials has generated inside the contemporary international. There are a few tries to chemically synthesize biodegradable polyesters such as polylactic acid and polyglycolic acid. The production of polyhydroxy alkanoates with the help of fermentation is the preferred technique for production of biodegradable plastics. There are typically two varieties of biodegradable plastic, injection molded and solid. The stable forms generally are used for objects such as food containers, leaf collection luggage, and water bottles. Bioplastics also can be processed in very similar methods to petrochemical plastics along with injection moulding, extrusion and thermoforming. To improve their tensile strength, bioplastic polymers may be combined with their co-polymers or with other polymers. Our biopolymers are suitable for a wide variety of catering and food-to-pass products, from thermoformed coffee cup lids to injection-molded cutlery and coatings for paper and board. Our plant-based products carry out in addition to oil-derived equivalents, and are 100% biodegradable and prepared to compost in conjunction with meals waste. Bioplastics provide a great solution, getting rid of the environmental impact without removing the packaging.</span><span style="color:#111111"> Our plant based polymers compost at the end of their useful life</span><span style="color:black">. Our products can be used for a huge range of packaging items, from number one and secondary packaging films, laminates and rigid sheets for thermoforming and vacuum forming, to point-of-sale display, trays and merchandisers. </span><span style="color:#111111">Bioplastics meet the demand for both long-life and cost-effective materials that underpin the sustainability of operations. Our product ranges are optimized for films, fibers, casting, molded and roto-molded items.</span></span><span style="color:#212121"> Nowadays, bio based polymers are commonly found in many applications from commodity to hi-tech applications due to advancement in biotechnology and public awareness.</span> In recent years, biopolymers with controllable lifetimes have become increasingly important for many applications in the areas of agriculture, biomedical implants and drug release, forestry, wild life conservation and waste management. Natural oils are considered to be the most important class of renewable sources. They can be obtained from naturally occurring plants, such as sunflower, cotton, linseed and palm oil<span style="background-color:white"><span style="color:black">. In Malaysia, palm oil is a cheaper and commodity material. </span></span>Biopolymer produced from palm oil (Bio-VOP) is a naturally occurring biodegradable polymer and readily available from agriculture. For packaging use however, Bio-VOP is not thermoplastic and its granular form is unsuitable for most uses in the plastics industry, mainly due to processing difficulties during extrusion or injection moulding<span style="background-color:white"><span style="color:black">. Hence, research employees have developed numerous methods to blend Bio-VOP as it should be for commercial uses. Specially, injections moulding strategies, graft copolymerization, and preparation of blends with thermoplastic polymers were studied to produce strong biodegradable formed bodies. HDPE become chosen as commercial thermoplastic materials and turned into introduced with 10% Bio-VOP for the preparation of solid biodegradable shaped our bodies named as HD-VOP. </span></span>The UV light exposure of HD-VOP at 12 minutes upon gives the highest strength of this material that is 17.6 MPa. The morphological structure of HD-VOP shows structure surface fracture which is brittle and ductile properties. Therefore, this study revealed the potential of HD-VOP to be used in industrial applications based on mass production.</span></span></p> </p> <p><b>Biography:</b> <p style="margin-left:0cm; margin-right:0cm"><span style="font-size:12px"><span style="font-family:Verdana,Geneva,sans-serif"><span style="background-color:white">Makhdoom Zada Arsalan Ahmed was born on 30<sup>th</sup> July, 1988 in Karachi Pakistan.

One of the most important aspects in the development of new forms of medication is focused on the design and application of controlled drug dosing systems and localized management systems for the activity of a particular drug. The current trend in such applications is the use of natural polymers such as chitosan, alginate or cellulose. Bacterial cellulose (BC) is a biopolymer synthesized by some bacterial strains which displays unique properties i.e. high crystallinity and purity degree, excellent mechanical performance, porosity and high swelling capacity attributed to the 3D nanofibrillar network structure formed during the biosynthesis process. Due to this last feature, BC can be considered a hydrogel. Depending on the cultivation technique used, BC can be obtained in different morphologies with variable properties. In dynamic cultures spherical particles can be obtained. BC obtained in dynamic cultivation presents a more disordered structure, higher porosity and higher water holding capacity. Moreover, to enhance and extend its applications in biomedicine and pharmacology, BC is normally modified to tailor its properties. One of the most attractive aspects, is that BC has the possibility to be modified through in situ methods, therefore BC-based composites can be obtained in one step procedure by the addition of some additives, polymers or particles to the culture medium so that the additive is incorporated into the BC growing nanofiber network during its biosynthesis. Among the materials that have been used in the in situ biosynthesis process of BC for the development of nanocomposites, graphene family materials can be found. Graphene oxide (GO) is a twodimensional monolayer carbon material which contains large number of hydrophilic oxygenated functional groups and this improves the miscibility of the GO sheets with other polymers included BC. Moreover, the reduced structure, reduced graphene oxide (rGO), exhibits excellent electrical and thermal conductivities and has attracted special attention for the development of conductive and stimuli-responsive systems. In the present work, GO has been incorporated in a BC sphere-like structure in dynamic cultivation by one step method. Different conformations have been obtained, from encapsulation to uniformly distributed hybrid spheres by the variation of the GO concentration during the BC biosynthesis. Hydrogels presented different swelling capacity, and semiconductive behavior, which could open new possibilities for the development of electrostimulated systems. Additionally, in order to evaluate the possible application of these hydrogels as nanocarriers for controlled drug release, the loading and release in simulated intestinal fluid of ibuprofen has been carried out</span></span></p> </p> <p><b>Biography:</b> <p><span style="font-size:12px"><span style="font-family:Verdana,Geneva,sans-serif">Leire Urbina obtained her Bachelor's Degree in Chemical Engineering at the University of the Basque Country (UPV/EHU).
